W3Techs tells you what the web uses. TechSpy tells you what one company runs.
W3Techs is the authority on adoption statistics across millions of sites. TechSpy points at a single domain and returns its real stack, infrastructure, and a decision-ready read.
- Point at one domain, get its real stack — not a percentage across all sites
- DNS, DMARC, subdomains and hidden APIs W3Techs was never built to surface
- Every scan ends in a Verdict, Evidence and Implications, not a raw list
Free — no card, 30 scans/day.
TechSpy — the read
HighVerdict
Modern Next.js front end backed by Segment and Intercom — but SPF passes while DMARC is set to p=none, so the domain is spoofable.
Evidence: Next.js on Vercel edge, caught via JS-runtime fingerprints; Segment, Intercom and HubSpot in the marketing stack; DMARC policy p=none — monitoring only, no enforcement.
Implications: A polished growth stack with an unguarded email domain — a clear opening for a vendor pitching deliverability or security.
Head to head
We're not pretending it's all checkmarks on our side — where W3Techsgenuinely wins, it's bolded.
What only TechSpy does
The depth W3Techsdoesn't reach — turned into an action, not a data dump.
🔍
Sees through the SPA
JS-runtime fingerprints and HTTP headers read React and Next.js apps that leave HTML scrapers near-empty.
🧭
A read, not a list
